opn_confirm_changes

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It discloses the 60-second timeout and auto-rollback behavior and that changes become permanent. However, it lacks details about side effects, authentication requirements, or exact return value structure beyond 'dict with confirmation status'.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise with three sentences, front-loading the key action and usage context. Every sentence serves a purpose without redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having an output schema (reducing need for return value description), the description omits explanation of the critical 'revision' parameter. It also does not mention prerequisites or how to obtain the revision from prior operations. For a simple tool with one parameter, this is insufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has one required 'revision' parameter with 0% schema description coverage. The description fails to explain what the revision parameter is, where to obtain it, or how it relates to the firewall changes. This is a critical gap for an agent to use the tool correctly.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool confirms pending firewall changes, cancels auto-rollback, and makes changes permanent. It uses specific verb-resource language and is distinct from sibling tools, many of which are add/delete/update operations, while this is a confirmation step.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly instructs to use the tool after applying firewall changes and mentions the 60-second auto-rollback. It provides clear context for when to invoke it but does not list when not to use or any alternatives, though alternatives are not needed for a unique confirmation step.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
